3343 5735 d 1 h decky /branches/sparc/ add sparc branch  
3249 5747 d 22 h jermar /trunk/kernel/doc/ Add Jiri Svoboda to AUTHORS and remove email addresses.  
3248 5747 d 22 h jermar /trunk/kernel/doc/ BUGS_FOUND is now out of date and it would require too much effort to keep it up
to date.
 
3228 5758 d 14 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
2500 6122 d 6 h jermar /trunk/kernel/ Make the kernel compile again after integrating the AVL tree.
Integrate with tests, add the AVL tree implementation author into AUTHORS.
 
2465 6173 d 3 h jermar /trunk/ Merge arm32 into trunk.  
2445 6180 d 3 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2061 6333 d 4 h jermar /trunk/ Improve comments and fix formatting in (sparc64) TLS implementation.
Improve some comments and formatting in sparc64 uspace thread library
code.

Update required msim version.
 
2001 6364 d 19 h jermar /trunk/kernel/ Indentation and comment fixes.  
1950 6402 d 0 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1915 6415 d 22 h jermar /trunk/kernel/ A quote from from SPARC V9 specification:

The Y register is deprecated; it is provided only for compatibility with previous versions
of the architecture. It should not be used in new SPARC-V9 software. It is
recommended that all instructions that reference the Y register (i.e., SMUL,
SMULcc, UMUL, UMULcc, MULScc, SDIV, SDIVcc, UDIV, UDIVcc, RDY, and
WRY) be avoided. See the appropriate pages in Appendix A, “Instruction Definitions,”
for suitable substitute instructions.

Still gcc is generating code which uses Y and some of the instructions above.
This change modifies the preemptible_handler() to preserve the Y register
across preemption.
 
1849 6468 d 6 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled.
 
1787 6504 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1761 6522 d 20 h jermar /kernel/trunk/doc/arch/ Upgrade amd64 hw compatibility list.  
1731 6528 d 17 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.
 
1705 6532 d 6 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1543 6543 d 7 h palkovsky /kernel/trunk/doc/ Note about mips bug making tetris to fail.  
1422 6550 d 6 h jermar /kernel/trunk/ Modify ia64 linker script to make compilation with gcc 4.1.x possible.  
1420 6550 d 7 h jermar /kernel/trunk/ Upgrade toolchain to use gcc 4.1.1.
ia64 still cannot be built with combination of binutils 2.16.1 and gcc 4.1.x
 
1323 6563 d 8 h jermar /kernel/trunk/ Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.

Also add one HT configuration to hardware compatibility list.
 
1297 6570 d 2 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1229 6583 d 5 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1169 6596 d 19 h jermar /kernel/trunk/doc/ Change developer emails to their aliases in helenos.eu.  
912 6632 d 21 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.
 
905 6635 d 19 h jermar /kernel/trunk/ Upgrade toolchain build scripts to install binutils 2.16.1 and gcc 4.1.0.
The only exception is ia64, where the kernel does not build with gcc 4.1.0.
 
832 6655 d 19 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
822 6657 d 19 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
812 6658 d 19 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
761 6664 d 5 h jermar /kernel/trunk/doc/ Remove document describing more relaxed preemption model than the one used in the current kernel.  
750 6667 d 22 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.
 
703 6684 d 5 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
681 6689 d 6 h jermar /kernel/trunk/ Minor changes.  
558 6721 d 3 h palkovsky /kernel/trunk/ Clean up of build system. Use:
make config
make
make clean
 
534 6723 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6723 d 22 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6730 d 2 h jermar /kernel/trunk/ Clean up.  
516 6733 d 23 h jermar /kernel/trunk/ Add VMware Workstation 5.5 to SMP compatibility list.
